Hi guys,

I have a Data East Checkpoint machine that is constantly resetting. some times it will play for a little while, but never enough to get a full game in.
I replaced one of the bridge rectifiers on the power supply board (DB1) and i thought that had fixed it, but after a weekend at a show it seems to have got a lot worse.

Does anyone have any idea what i should look for next?

Thanks,
Eric

Thanks for the link, I have ordered a load of spares to try to rebuild it.
After the game resets, it reads the following message...

'Command Overrun / A017'

Does that mean anything to any one?
